Hazard statements
H220:Extremely flammable gas. H281:Contains refrigerated gas; may cause cryogenic burns or injury. May displace oxygen and cause rapid suffocation. May form explosive mixtures in air. Burns with invisible flame.
Prevention
P210:Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources. No smoking.
Response
P377 Leaking gas fire Do not extinguish, unless leak can be stopped safely P381 :Eliminate all ignition sources if safe to do so.

2.3 Other hazards
Burns with an invisible flame. Can ignite on contact with air. Extremely cold liquid and gas under pressure. Extremely flammable liquefied gas. Vapors may spread long distances and ignite. Direct contact with liquid can cause frostbite. Avoid breathing gas. Can cause rapid suffocation. Self contained breathing apparatus (SCBA) may be required. High concentrations that can cause rapid suffocation are within the flammable range and should not be entered. Immediate fire and explosion hazard exists when mixed with air at concentrations exceeding the lower flammability limit (LFL). 100 % of mixture consists of ingredients of unknown acute toxicity
